Help with OGG/OGM files

hi, im not quite sure if this goes here, but i was wondering how to convert an OGM file to wmv so i can put it on a pda? i tried coverting it to avi then to wmv using river past video cleaner then windows media encoder, but the video stops at the first frame, is there anythign i can do? thanks

okay it was a ogm file, i didn't know, but i gave up on that, i have windows media encoder 9 and when i select an avi file to conver to wmv it just freezes is there anything i can do about this? i want to make it a wmv so i can watch it on my pda thanks
